IMPROVEMENT IN M A CHINES FOR WINDING BOBBINS.

Specification forming part of Letters Patent No. 125,564, dated April 9,1872; antedated March 29, 1872.

To all whom it may concern.-

Y Be it known that I, WILLIAM V. GEE, of Philadelphia, in the county ofPhiladelphia and State of Pennsylvania, have invented a new and valuableImprovement in Machines for Winding-Bobbins and I do hereby declare thatthe following is a full, clear, and exact description of theconstruction and operation of the same, reference being had to theannexed drawing making a part of this specification, and to the lettersand figures of reference marked thereon.

Figure 1 of the drawing is a representation of a top view of myinventionwith upper plate removed. Fig. 2 is a side-view. Fig. 3 is ahorizontal section of the same.

This invention has relation to improvements in machines for windingbobbins; and it consists in a novel combination of machinery for thatpurpose, hereinafter fully described. The object of the invention is toprovide a machine for the automatic winding of thread on bobbins, so asto secure uniform tension and com-' pact and tight winding of the threadthroughout.

Referring to the accompanying drawing, A represents a frame suitable forthe support of the machinery. B B are driving-shafts parallel to eachother, and supported in proper bearings on the frame A. Suitableprovision is made on the end 11 of the shaftB for the ap- The drums C 0,carried by the shafts B B are of like dimensions and form, each being inthe shape of a frustum of a cone. They are placed directly opposite toeach other on the end of the shafts B B so that the large end of the oneis opposite to the small end of the other. Their circumferentialsurfaces are furrowed to aid in giving motion to the belt or cord 01,which transmits motion from one to the other. The drum 0 has connectedto its small end the pulley c, which carries the belt or cord 01 thattransmits motion from the drum 0 to the pulley c, on the shaft E. Thesmall pulley c on the end of the shaft B carries the crossed belt orcord d, which transmits reverse motion from the shaft B to the largerpulley 0 The pulleyc has a lateral bearing in the frame A, and on itsother side a pinion-wheel, f, which transmits motion from the pulley cto the cog-wheel F. The cog-wheel F revolves on a fixed spindle thatprojects from the frame A, and has on its inner side around the spindlea heart-shaped hub or eccentric, f, which acts as a cam, and transmitsan alternating reverse motion from the cog-wheel F to the arm g. The armgis fixed to the shaft B and drawn against the eccentric f by the springh. It works in the forked end of the elbowed lever t, which is sustainedat its angle by a support projecting from the frame A. The lever 1;transmits the alternating reverse motion from the arm g, by means of itsslotted end and a connecting-pin to the sliding bar is, which issupported by guides in the frame A, and in a projection from it. The barIt has on its end a double vertical slotted guide, 0, through which thebelt or cord (1 passes, and by. means of which the alternating reversemotion is transmitted from the bar 70 to the belt at. The arm 9transmits the alternating reverse motion from the eccentric f to theshaft B which is supported in bearings projected downward from the frameA, and which transmits a like motion to the upwardly projecting arm 9that is adjusted on the shaft B by a collar and setscrew. The arm g has,at its upper end, a lateral projection or boss, m, that serves as aguide for the thread and an aid in regulating its motion and tension,transmitting to it the alternating reverse motion from the arm 9 Thebent support 10 rests at its ends upon the frame A, and has upon itsupper side the fixed vertical projecting-arms g 9 The arm g has at itsupper end a lateral boss, m m, to support the thread. The arm g has nearits middle a lateral horizontally slotted guide throughwhich 7 passesthe sliding rod k, notched on its side so as to catch against the edgeof the arm The sliding rod 7c is free at one end for the application ofthe hand, and is connected at the other to the lever '5 which issupported on a downWardly-proj ecting-arm from the frame A, by anadjustable pivot. Supported on a lateral bearing on the lower end of thelever i is I the pulley e which presses against the belt or cord d. Bymeans of the sliding rod k, lever 6 and pulley c", the tension of thebelt or cord at is regulated at will, so that the bobbin-shaft E mayormay not be revolved. The bobbin-shaft E has its bearings at one end intwo fixed supports projecting downward from the frame A, one on eachside of the pulley 0 From the lower end of the support a, a bent guardprojects to prevent the belt or cord 11 from slipping off of the pulley0 The other end of the shaft E has its bearing in a remoyable support,12 which is hinged to the frame A at p, and held in place or released atwill, by a spring-catch, p, on the frame A. The arm 9 has its bearing onthe upper end of the arm 9 and is provided at the other end with asuitable guide, Z, for the thread, which passes under and over a supportprojected from the arm 9 It is also provided with a lug, o, for thepurpose of disengaging the sliding rod k from the arm 1 so that shouldthere be any unusual strain on the thread the arm g will be raised, andthe sliding rod k disengaged as aforesaid, and, as before shown, themotion of the bobbin stopped. The bobbin R is of the genera-l formshown, and may be slipped on or off of the shaft E, the bearing supporta being turned down first. The clutch to slides in a groove in the shaftE, and by means of lugs on its face fitting in corresponding recesses inthe end of the bobbin It. the bobbin R is fixed on and takes therevolving motion of the shaft E. A revolving-plain faced pulley, WV, issupported in close proximity to the bobbin R on a lateral spindle on thebent arm 9 extending from the bent support 19 so that the face of thepulley NV and the face of the conical portion of the bobbin It. at theirnearest line, are parallel. The pulley W serves to secure uniform andcompact winding of the thread, and to press back the bobbin 1% on theshaft, as the thread accumulates. The pulley WV may be of any desiredform, as conical or cylindrical.

\Vhen the machine is in operation, the thread passes from its sourcearound under the guide 1 and over the supports m m to the bobbin 1%. Thebobbin R is so placed 011 the shaft E, that the alternating reversemotion of the arm 9 causes the thread to wind with a like motion overthe conical furrowed surface of the bobbin It. As the threadaccumulates, the pressure upon the pulley Wcauses the bobbin B to slidebackward toward the end of the shaft E, and thus each layer of thread iskept parallel with the first, and with the conical surface of the bobbinR. As the belt or cord d moves laterally over the drums O G, the motiontransmitted from the drum G to the drum 0, and consequently to thebobbin R is varied. When the belt or cord '61 is at the large end of thedrum 0 it is at the small end of the drum 0, and in consequence themotion of the drum 0' and the bobbin It is most rapid, and vice versa.This varied motion of the bobbin R is necessary to secure uniformtension of the thread, as it winds over the conical surface, for thevelocity of different points in a line with the length of the bobbin onthe conical surface with uniform motion of the bobbin varies, beingslower towards the point; and hence as the thread winds down thesurface, it is necessary to increase the speed of the bobbin tocompensate for this diminished velocity, and vice versa. The pulleyW isset in motion by the revolving surface of the bobbin R or the threadthereon, and aids materially in producing uniform tension, and tight andcompact winding of the thread, es-

pecially as the thread approaches the smallest part of the conicalsurface, or the point of the bobbin, which result it has been,heretofore, very diff cult to attain.
